MANUFACTURE OF GLASSWARE.
Application filed May 2,
I '0 all whom it may concern Be it known that I, Ronnn'r Goon, a citizen of the United States, residing at 1V ashington, ,l/Vashington County, Pennsylvania, have invented new and useful Improvements in the Manufacture of Gliissware, of which the following is a specification, reference being had to the accompany ing drawings, in whicha Fig. 1 is a partial section of a glass furnace or tank showing the application of my invention thereto; Figs. 2, 3, 4 and 5 are, respectively, sections on lines IIII, IIL-III, IV-JV and VV of Fig. 1; Fig. 6 shows in side elevation partly insection the paddle mechanism; Fig. 7 1s a section on lines VII-VI'I of Fig. 6; and.
Fig. 8 is a'plan thereof.
My invention relates to the delivery of glass from a furnace or tank, and comprises providing atank with a channel or trough I leading from the molten glass in the furnace claim.
to a position in which the glass may be gathered and thence back into the furnace, so that very hot and homogeneous glass may be caused to flow from the furnace to the gathering position and the glass chilled by the gathering operation is carried back into the furnace, leaving a new and hot supply of glass for the next implement to operate upon. MyIIIVGIItIOH also consists in the shape of the trough, the furnace breast arrangement, the means for causing the fiow of the glass, as well as in the construction and arrangement of parts which I shall hereinafter describe and Referring to the drawings, 2 indicates the walls of a furnace or tank, which may be a glass melting furnace of any approved type. Projecting forwardly from the front wall is a channel or trough 3 to which glass is supplied fromthe body of glass in the tank through a hollow block 4, thebottom of which opens into the tank at a distance below the surface of the glass so that only the very hot and thoroughly molten glass will be able to flow out into the trough 3. In the. discharge and 5 of the trough, where it re-enters the furnace, a paddle 6 preferably reciprocating is arranged, which pushes or causes the glass to flow from the trough 3 back into the furnace,
as is best shown in Figs. 1 and 4. The displacement of the glass effected by the paddle 6 in the discharge end 5 of the trough gathering 1921. Serial No. 466,117.
induces a flow of hot glass upward through the block 4 and through the trough 3. The glass in the trough is kept from chilling unduly b the 'hot gases which escape through t e slot 7 between the lower edge of the breast 8 of the furnace and the upper surface ofthe inner side of the trough.
To control the temperature of glass flowing through the trough 3 I have shown a water cooled device 9 for obstructin the channel or trough 3, which is shaped ike a comb. The teeth ofthe comb 9 may be lowered into the surface of the glass to diminish the temperature of glass flowing through the trough 3.
As my improved furnace is designed primarily for the delivery ofv glass to forming devices rotating on the circumference of a circle such as machines of the Owens type, I have shown the walls 10 of the trough 3 curved to the radius of such a form-- proximately through the center of the trough. This ensures the obtaining of a hot and homogeneous supply of glass, as the curvature of the trough will prevent the gather ing devices from gathering glass near the sides of the trough, where it may have become chilled.
The paddle mechanism consists in a water cooled paddle 6 mounted ona shaft 11, the rear end of which is mounted in bearings 12 in a bracket 13 to permit rotation about its own axis, and the bracket 13 is pivoted.
on a vertical axis to a standard 14to permit reciprocatory motion of the paddle.- The paddle shaftll has upon it a sleeve 15 by which it is supported in a block 16. The block 16 is swiveled to a carrier 17 fixed on the rods 18, which reciprocate in bearings 19 on the frame 20. The sleeve 15 has upon one of its ends a bearing 21 for a lever arm 22 connected by a link- 23 to the bell crank 24:; The bell crank 24; is pivoted to the frame and has upon its extension 25 a weight 26 which forces the long-arm of the bell crank 24 and the paddle shaft 11 through the link 23 and lever arm 22 in one direction, while the heart-shaped cam 27, which engages a roller 28 on the long arm of the bell crank 24, causes movement of the bell crank and through it the acidic shaft 11 in the opposite direction. The cam is: actuated through the pulley 29, which is mounted on the cam shaft 30 from any suitable source 51?" from the furnace below the level of the glass and an e'xit opening into the channel.
' When the cam 27 is set in rotationgages the roller 28, as is best shown in Fig.
. and forces the long arm ofthe bell crankf 24 to the left against the action of the- Weight 26. This causes the paddle shaft to rotate to the left and clear the paddle fromthe glass, and also causes the shaft and with it the paddle in horizontal position to move to the left on the back stroke.
When the paddle has been moved to the' dotted line position shown in Figs. 1 and 4 the rotation of the cam 27 permits the weight 26, through the crank 24 and link 23, to cause the lever arm 22 to rotate the paddle shaft 11 and with it the paddle into vertical position, and at the same time forces the shaft and paddle to the right, and the paddle pushes the glass in front of it back into the furnace.
The terms and expressions which I have employed are used as terms of description and not of limitation, and I have no intention, in the use of such terms and expressions, of excluding any mechanical equivalents of the features shown and described, or portions thereof, but recognize that various structural modifications are possible within the scope of the invention claimed.
What I claim is:
1. In apparatus for making articles of glass, a furnace or tank, a channel fOr the molten glass communicating at both of its ends with the main body of the glass in the-furnace, means for causing glass to flow through said channel and back into the furnace whereby a hot and homogeneous supply of glass is maintained in said channel for a gathering mechanism, the walls of the channel intermediate its ends being curved on the arc of a circle described by the movement ofthe gathering mechanism.
2. In apparatus for making articles of glass or the like, a furnace or tank, a channel for the molten glass communicating at both ends with the main body of glass in the furnace, means for causing the glass to flow through said channel, the entrance from the furnace into the channel comprising a hollow .block haiiing an entrance opening 3.
